CATCH-BASIN.

SPECIFICATION forming part of Letters Patent No. 377,056, dated January31, 1888.

Application filed November 9, 1887.

To aZZ whom it may concern:

Be it known that 1, JOHN WIEDMANN, a citizen of the United States, and aresident of Oincinnati,-in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Catch-Basins, ofwhich the following is a specification.

This invention is an improved catch basin, and relates more particularlyto an improved means for breaking up the more solid substances, so thatthe basin is not liable to clog, and can be readily cleansed wheneverdesired.

The invention consists in certain novel arrangements and combinations toaccomplish this result, all of which will be first fully described inconnection with the accompanying drawings, and then particularlyreferred to and pointed out in the claims.

Referring to the drawings,Figure 1 is a central vertical section of acatch-basin provided with my improvements. Fig. 2 is a transversesection of the central cage and its connections, taken through line :000.

Referring to the parts,which are represented by similarreference-letters wherever they oc cur throughout the various views, Arepresents a basin of ordinary construction, the bottom being preferablyinclined toward the central discharge-pipeB,which leads to the sewer.Directly over this central discharge is placed a cast-iron cage, thebase 0 of which is firmly embedded in the cement door or bottom of thebasin. The periphery of the bottom is beveled from the top outward, andthe top of the basin is dished toward the center opening, the edges ofwhich form a seat for the verticallymoving valve D. The top of the cage,G,is connected to the bottom by three pillars, Oflwhich are providedwith cutting-blades c, which project radially inward. The whole cage,including the top, bottom, and intervening pillars with theircutting-blades,is preferably cast in a single piece.

The top of the cage,G,is centrally perforated to receive and furnish abearing for the downwardly-projectinghubof the cogwheelE. The projectingcogged rim of this wheel rests upon the top 0, and its teeth mesh with apinion, F, which is secured upon the shaft f, which ex- Serial No.254,668. (No model.)

tends up through the seat G, and is provided at the top with ahand-wheel, F, by which the shaft-cog and pinion are rotated. Thecogwhcel E is centrally perforated to allow the valve-rod d to slidethrough it. The wheel E has also one or more angularperforations toreceive one or more shafts,H, which shafts carry cutting-blades h, whichproject radially outward in a position to pass the stationaryinwardly-projecting cutters 0, when the wheel is revolved,the two setsof blades acting together as breakers to dispose of the larger or moresolid substanceswhich would be likely to clog the discharge-pipe. Thetop 0 is perforated to form the lower bearing for the shaftf. Its upperbearing is on top of the seat. The valverod d also projects through theseat, to insure a vertical movement for seating and unseating the valveD. The valve is raised by means of treadle-arm I, which projects throughthe side of the seat in a convenient position to be operated by the footby the person who may be turning the wheel F, in order that as fast asthe heavy matter is broken up it may, before settling, be discharged.

I have shown in dotted line, Fig. 1, a light sheet-metal housing to keepall the substances from the cogs which would be liable to clog them, andat J, I have represented the overflow, which is also to be connected tothe sewer-pipe.
